3. Swimming pool

Open air swimming pools that are heated using
mains electricity can use as much as 1000kWh
every day.

They use more energy if they are:

bigger.

have warmer water.

the outside air is cooler.

Cleaning pools also uses energy. A single pool can put up to 160 tonnes of carbon dioxide gas
(the volume of nearly 7million double-decker buses)
into the atmosphere each year. Carbon dioxide
harms the environment.

Can this school teach swimming, but cause
less damage to the environment?
